Country / Area: Italy

Classification category: Expenditure classifications

1 (a)Name of the current national classification (full name in official national languages and in English with acronyms in brackets, should be given)“Classificazione dei consumi individuali secondo lo scopo revisionata dall’Istat” – “Classification of Individual Consumption by Purpose revised by Istat” (COICOP Rev. Istat).

This classification is used for CPIs.

1 (b)In which language(s) is the classification available?Italian, English
1 (c)Can the classification (or information about it) be accessed on the Internet? If yes, please provide the URL. 
Classification structure
2 (a)Please describe the structure of the classification: How many levels does the classification have? (Please provide labels, such as “Division”, “Class”) How many categories exist at each level?The classification COICOP Rev. Istat has 5 levels.

Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.COICOP Rev. Istat is based on the UN-COICOP (the first 4 digits XX.X.X correspond to UN-COICOP classes).

The 5-digit level is based on the Eurostat proposal of the harmonized 5-digit COICOP (the first 5 digits XX.X.X.X correspond with very few changes to sub-classes of draft version COICOP-5 of July 2010).

The 6-digit level was defined using as base the draft version of the COICOP/HICP–6 carried out by the Task Force Classification COICOP/HICP which was set up by the HICP WG in 2004 and finished its works in 2005 (the first 6 digits correspond to COICOP/HICP-6 consumption segments; for this level there are several differences from COICOP/HICP-6 which consist in consumption segment aggregations).

3 (b)Is the classification structure identical to the international standard or, if not, how does it differ? (e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)COICOP Rev. Istat structure has two additional levels added to the UN-COICOP.
It has one additional level added to Eurostat COICOP-5 (draft version of July 2010).
Compared to COICOP-5, it shows very few differences which consist in aggregations of some sub-classes.
3 (c)Please describe deviations from the international standard (in terms of structure, methodology or application rules). Please use examples, if a general statement is not possible.The differences are those mentioned above in 3 (b).
3 (d)At what level of the international standard can data be reported for international comparison? (Please provide examples of programmes / indicators if reporting takes place at different levels of the classification.)At all three levels (division, group and class) of UN-COICOP.
3 (e)If no links to international classifications exist or no international standard is used, please state if there are plans to use international norms in the future. 
Classification uses
4 (a)Please state for which statistical purposes (surveys etc.) this classification is used and if there are users outside of the Statistical Office. Please indicate at which level the classification is used for data collection and for data publishing.The COICOP Rev. Istat classification is used for the calculation of CPIs. The level of consumption segments (6-digit) is used for CPIs data publication.
With regard to data collection, the Consumer Price Survey refers to a basket of products which are selected inside each consumption segment. Each product is identified by a code of 10 digits where the first six digits correspond to 6-digit level of COICOP Rev. Istat.
4 (b)Please give the names of institutions that use the classification for non-statistical purposes (as opposed to statistical purposes in question 4(a)). Also indicate the kind of use (e.g. tax offices, social security, customs, enterprise register, employment services, work permits etc.) 
4 (c)Please indicate if alternative classifications are used by other institutions of the economy. Are these classifications available and useful for the Statistical Office? 
Implementation / revision status
5 (a)Please state the date of the official adoption of the classification. If not yet adopted, please indicate the current state (e.g. in development, sent for approval, in printing, ready to be distributed etc.)The date of the official adoption of COICOP Rev. Istat is the year 2011.
5 (b)Please state the date of use of the classification for individual statistical programmes.Year 2010
5 (c)Are there existing plans for revision or update of the current classification?An updating of the current classification, which will entail few changes, is foreseen in the next years, when the final version of the harmonized COICOP-5 will be adopted by Eurostat for HICP, PPP and HBS.
5 (d)Name of former (previous) national classification (full name in both national tongue and in English with acronyms in brackets, should be given)“Classificazione dei consumi individuali secondo lo scopo per gli indici utilizzata per gli indici dei prezzi al consumo” (COICOP NIC) – “Classification of Individual Consumption by Purpose for Italian CPIs” (COICOP CPIs)
